Darlyne Markus was 29 years old when she started delivering papers for the Idaho Press-Tribune in Nampa, Idaho. That was in 1958. The now 83-year-old recently retired after 54 years, still holding the Guinness World Record for longest-serving paper girl. Markus worked seven days a week from 1 to 4 a.m. and traveled 43 miles on her route.

“She was always, always concerned about customers,” her daughter, Nancy Salisbury, told the Press-Tribune. “If she got a call that somehow they got missed, she would be in the car, in her robe, in her slippers, jetting the paper out to them.”
